May you could use an absolute reference using
${PROJECT_SOURCE_DIR}/libs/global/win32_spec.h
if your project is name TOTO
(from the PROJECT(TOTO CXX) statement)
you use
${TOTO_SOURCE_DIR}/libs/global/win32_spec.h.

You may use a CACHED variable
set(WIN32_SPEC ${PROJECT_SOURCE_DIR}/libs/global/win32_spec.h CACHE
FILEPATH "Central Include")
the first calling this will set the value then other set will be ignored.
If you want to override a CACHE var value you'll have to use FORCE set option.
