[CMake] Add search paths for FIND_PACKAGE ?

[David Cole]

So for the specific case you ask about, FindCURL.cmake, you would set the
following advanced variables during ccmake / CMakeSetup configure through
the cmake GUI:CURL_INCLUDE_DIR
CURL_LIBRARY

Then, with those set, the next FIND_PACKAGE(CURL) will "find" CURL because
you've told it exactly where it is.

If you do it all with cmake without a GUI, then you would specify those
variables on the first cmake command line with -D.


Does that help?
David
