You also need to set the value in the cmake file BEFORE calling the
configure_file() command. So what you really want is the following:
*.cmake file
set( TEST_VAR_VALUE 0 )
configure_file( ${PROJECT_SOURCE_DIR}/src/config.h.in
${PROJECT_SOURCE_DIR}/src/configure.h @ONLY)
and in your config.h.in you will have:
#define TEST_VAR_VALUE @TEST_VAR_VALUE@
This results in TEST_VAR_VALUE _always_ being defined in your
program. It will be defined to what ever you set it to in the *.cmake
file.
