You should instead write those GIT variables in a file, like this: file(WRITE ${CMAKE_BINARY_DIR}/git_version.h.in " #define GIT_SHA1 \"@GIT_SHA@\" #define GIT_TAG \"@GIT_TAG@\" #define GIT_LOCAL_CHANGES \"@GIT_LOCAL_CHANGES@\"" ) configure_file(${CMAKE_BINARY_DIR}/git_version.h.in ${CMAKE_BINARY_DIR}/git_version.h @ONLY) Make sure you have ${CURRENT_BINARY_DIR} as part of your target's include directories. And then somewhere in your code do an #include "git_version.h". Cheers, Cristian.
