Re: [CMake] problem with cmake script.

2009-03-09 Thread Adolfo Rodríguez

I was also fooled by that sentence some time ago, but careful reading of
what the doc says after "If NO_DEFAULT_PATH is not specified, the search
process is as follows:" suggests something different.

What I currently do to solve the issue of nonstandard package locations is
to use an environment variable called Foo_ROOT_DIR (for package Foo), as
suggested 
here.
If you're interested, I could send you a FindOpenCV.cmake script that works
like this.

Cheers,

Adolfo

Re: [CMake] problem with cmake script.

2009-03-09 Thread Adolfo Rodríguez

Hi Benoit,

The documentation of
find_pathspecifies
the order in which paths are searched. If you want to force the
/opt path to be searched first, you should maybe try

find_path( NAMES name PATHS ${NONSTANDARD_PATHS} NO_DEFAULT_PATH)
find_path( NAMES name)

This part is documented at the very end of the find_path doc.

Nope but did you carefully read  the help of find_path
concerning the rule used for search path?

http://www.cmake.org/cmake/help/cmake2.6docs.html#command:find_path

may be the explanation is already there.
