[LLVMdev] CMake configuration: Detecting zlib.h header in windows.
Hi, I have having hard time to let cmake configuration detect the zlib header in windows with "Visual Studio 12" generator. My cmake configuration goes like >> Set path, include and lib environment variables to point to zlib headers and libraries. Cmake version is 2.8.12.2 cmake -G "Visual Studio 12" -D LLVM_TARGETS_TO_BUILD:STRING=%TARG% -D TARGET_TRIPLE:STRING=%TRIPLE% -D LLVM_DEFAULT_TARGET_TRIPLE:STRING=%TRIPLE% -D LLVM_TARGET_ARCH:STRING=%TRIPLE% -D LLVM_ENABLE_PIC:BOOL=ON -D LLVM_ENABLE_ASSERTIONS:BOOL=ON -D CMAKE_INSTALL_PREFIX=%win_top_install_dir% -D CMAKE_BUILD_TYPE=%BLDMODE% -DLLVM_APPEND_VC_REV:BOOL=ON -D LLVM_VENDOR_NAME:STRING=%NAME% -D LLVM_VENDOR_VERSION:STRING=%VER% %win_top_src_dir%/llvm As far as I know, cmake tries to compile a simple file with "#include <zlib.h>" with MSbuild.exe which invokes a project file. MSbuild has its own environment and ignores the user's environment variables. Any one face this issue before? Let me know if you need more details on this. The bottom line is , I want to set HAVE_ZLIB to 1
