Hi
I just started testing 3.5.0-rc1 on Linux and I noticed regression in
Makefile generation time.
I checked 3.5.0rc1, 3.4.3 and 3.2.2 versions, and the results are as
follows:
64bit cmake 3.5.0-rc1 Makefile Generation
1. Run
real 2m36.457s
user 2m32.008s
sys 0m3.184s
2. Run
real 2m36.764s
user 2m31.672s
sys 0m3.296s
64bit cmake 3.4.3 Makefile Generation
1. Run
real 1m29.679s
user 1m24.696s
sys 0m2.920s
2. Run
real 1m28.266s
user 1m24.220s
sys 0m2.976s
64bit cmake 3.2.2 Makefile Generation
1. Run
real 1m57.894s
user 1m54.160s
sys 0m2.320s
2. Run
real 1m57.083s
user 1m53.076s
sys 0m2.304s
Is it known issue?
Do you have suspects what could cause this regression?
Best Regards

> I am proud to announce the first CMake 3.5 release candidate.
>
> Sources and binaries are available at:
> https://cmake.org/download/
>
> Documentation is available at:
> https://cmake.org/cmake/help/v3.5
>
> Release notes appear below and are also published at
> https://cmake.org/cmake/help/v3.5/release/3.5.html
>
> Some of the more significant features of CMake 3.5 are:
>
> * The precompiled Windows binary provided on "cmake.org" is now a
> ".msi" package instead of an installer executable. One may need to
> manually uninstall CMake versions lower than 3.5 before installing
> the new package.
>
> * The "cmake-gui(1)" learned an option to set the toolset to be used
> with VS IDE and Xcode generators, much like the existing "-T" option
> to "cmake(1)".
>
> * Find modules for Boost, FLEX, GTest, GTK2, PNG, TIFF, and XercesC
> now provide imported targets.
>
> * The "FindOpenMP" module learned to support Clang.
>
> * A new platform file for cross-compiling in the Cray Linux
> Environment to target compute nodes was added. See Cross Compiling
> for the Cray Linux Environment for usage details.
>
> * The "Compile Features" functionality is now aware of features
> supported by Clang compilers on Windows (MinGW).
>
> * Support was added for the ARM Compiler (arm.com) with compiler id
> "ARMCC".
>
> * When building for embedded Apple platforms like iOS CMake learned
> to build and install combined targets which contain both a device
> and a simulator build. This behavior can be enabled by setting the
> "IOS_INSTALL_COMBINED" target property.
>
> * The "CPackDMG" module learned new variable to specify AppleScript
> file run to customize appearance of "DragNDrop" installer folder,
> including background image setting using supplied PNG or multi-
> resolution TIFF file. See the "CPACK_DMG_DS_STORE_SETUP_SCRIPT" and
> "CPACK_DMG_BACKGROUND_IMAGE" variables.
>
> Deprecated and Removed Features:
>
> * The "CMakeForceCompiler" module and its macros are now deprecated.
> See module documentation for an explanation.
>
> * The "cmake(1)" "-E time" command now properly passes arguments
> with spaces or special characters through to the child process.
> This may break scripts that worked around the bug with their own
> extra quoting or escaping.

>
> * The "cmake-gui(1)" learned an option to set the toolset to be used

>
> * The "cmake-gui(1)" gained a Regular Expression Explorer which may

>
> Command-Line
> ------------
>
> * The "-Wdev" and "-Wno-dev" "cmake(1)" options now also enable and
> suppress the deprecated warnings output by default.
>
> * The suppression of developer warnings as errors can now be
> controlled with the new "-Werror=dev" and "-Wno-error=dev"
> "cmake(1)" options.
>
> * The "cmake(1)" "-E" command-line tools "copy",
> "copy_if_different", "copy_directory", and "make_directory" learned
> to support multiple input files or directories.
>
>
> Commands
> --------
>
> * The "cmake_parse_arguments()" command is now implemented natively.
> The "CMakeParseArguments" module remains as an empty placeholder for
> compatibility.
>
> * The "install(DIRECTORY)" command learned to support "generator
> expressions" in the list of directories.
>
>
> Variables
> ---------
>
> * The "CMAKE_ERROR_DEPRECATED" variable can now be set using the
> "-Werror=deprecated" and "-Wno-error=deprecated" "cmake(1)" options.

>
> * The "FindGTK2" module, when "GTK2_USE_IMPORTED_TARGETS" is
> enabled, now sets "GTK2_LIBRARIES" to contain the list of imported
> targets instead of the paths to the libraries. Moreover it now sets
> a new "GTK2_TARGETS" variable containing all the targets imported.
>
> * The "FindOpenMP" module learned to support Clang.
>
> * The "FindOpenSSL" module gained a new "OPENSSL_MSVC_STATIC_RT"
> option to search for libraries using the MSVC static runtime.
>
> * The "FindPNG" module now provides imported targets.
>
> * The "FindTIFF" module now provides imported targets.

> "Source" field using a monolithic or per-component variable. See
> "CPACK_DEBIAN_PACKAGE_SOURCE".

> control fields per-component. See variables
> "CPACK_DEBIAN_<COMPONENT>_PACKAGE_SECTION" and

> DMG. See the "CPACK_DMG_SLA_LANGUAGES" and "CPACK_DMG_SLA_DIR"
> variables for details.
>
> * The "CPackNSIS" module learned new variables to add bitmaps to the
> installer. See the "CPACK_NSIS_MUI_WELCOMEFINISHPAGE_BITMAP" and
