Summary0015702: FindBoost ignores Boost_NO_SYSTEM_PATH in debug builds
DescriptionIt seems the FindBoost module in Clion 1.1's new cmake ignores the Boost_NO_SYSTEM_PATHS for a Debug build, selecting /usr/lib64 instead of the correct library path, resulting in link errors.

I had to do this to make the Debug configuration work:

Work around FindBoost locating debug libs in the /usr/lib64 instead of the custom installation
SET(Boost_LIBRARY_DIR_DEBUG $ENV{HOME}/usr/local/boost/lib CACHE PATH "Forced boost lib dir for debug" FORCE)
SET(Boost_PROGRAM_OPTIONS_LIBRARY_DEBUG $ENV{HOME}/usr/local/boost/lib/libboost_program_options-gcc49-mt-1_56.so CACHE FILEPATH "Forced boost program_options lib dir for debug" FORCE)


Here is the cmake output showing the incorrect Boost_LIBRARY_DIR_DEBUG

Steps To ReproduceTry to link a boost program using a custom installation of Boost in your home directory with a different, incompatible one installed by default in the Linux OS filesystem.
Additional InformationThis worked fine until I updated to this version with the latest CLion.

 For me on CMake 3.5.1, Boost_NO_SYSTEM_PATHS find system libraries, too. Either documentation is wrong or this is a bug.

 Please run CMake with -DBoost_DEBUG=ON to get more verbose output about what FindBoost is doing.

 It is very easy.
Do:

set( BOOST_INCLUDEDIR "nonpresent" )
set( BOOST_LIBRARYDIR "reallybad" )

set( Boost_NO_SYSTEM_PATHS ON )

find_package( Boost REQUIRED
    COMPONENTS
        filesystem
)

# This does NOT fail (see documentation). It finds filesystem in system.

I do not know, whether this is the same issue as the original post.

 A change in CMake 3.3 extended what system paths are found via the environment:

 Teach find_(library|file|path) to get prefixes from PATH
 https://cmake.org/gitweb?p=cmake.git;a=commitdiff;h=ffc06c12 [^]

That exposed the actual bug in FindBoost which is that it should not consider system environment variables either when Boost_NO_SYSTEM_PATHS is given. I've fixed that now:

 FindBoost: Fix Boost_NO_SYSTEM_PATHS to not consider environment
 https://cmake.org/gitweb?p=cmake.git;a=commitdiff;h=5a9b2b3b [^]

Please try this fix locally to see if it resolves the issue.

 With the fix it fails again.
