Hi
One more thing.
There is huge difference in Unix Makefile generation time between 32 vs 64
bit cmake version:
32 bit CMake 3.5.0 generation time:
real 5m33.310s
user 5m27.268s
sys 0m3.540s
64 bit CMake 3.5.0 generation time:
real 2m36.457s
user 2m32.008s
sys 0m3.184s
Unfortunately there no 64bit CMake version for Windows:
https://cmake.org/download/
Is it possible to create 64 bit build for Windows?
Best Regards
Bartosz

>> 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.

>> variables for details.
>>
