Hi guys
I'm not able to convince cmake to properly use an environment variable which
consists of more than one entry for the INCLUDE_DIRECTORIES directive. It always
takes the value as it is:
Passing
MY_SPECIAL_INCLUDE32=/foo/bar/32bit/include:/foo/bar/include
to INCLUDE_DIRECTORIES like
INCLUDE_DIRECTORIES( "$ENV{MY_SPECIAL_INCLUDE32}" )
results in
/usr/bin/c++ -I/foo/bar/32bit/include:/foo/bar/include ...
instead of
/usr/bin/c++ -I/foo/bar/32bit/include -I/foo/bar/include ...
What happens if you use the correct CMake list delimiter ";" rather than ":"
to separate the two include directories? IOW, as a test try
INCLUDE_DIRECTORIES("/foo/bar/32bit/include;/foo/bar/include")
I haven't tried that, but it may work.
If that works, then you could (a) ask your users to use a
semicolon-separated list of directories (which is probably a little
confusing and unnatural for them) or (b) continue with a colon-separated
environment variable, but transform it in CMake with STRING to replace ":" by
";" before using it as a list.
