Hi, I'm new to CMake -- trying to do something relatively simple. Not
having much luck -- I've scoured the docs/wiki, but searching the manual
http://cmake.org/cmake/help/v2.8.9/cmake.html in the browser results in a
million hits for a search string.
I just want to test if an environment variable is set and if it is not,
print a message and exit
Something like:
if("$ENV{FOO_HOME}" MATCHES "")
message("You must set FOO_HOME")
return()
endif()
This does not seem to work. I've tried setting and unsetting $FOO_HOME,
and the if condition always applies.
What am I missing
