Hi all,
Hi all. First time posting. Before I start I'd like to thank all the Kitware
guys for a very nice and useful tool. I did a fair bit of searching to try
to avoid asking duplicate questions, but did not find answer to my problem.
I am trying to make a private build of some dependencies, ogg and vorbis in
this case. The initial problem is that second library make is not finding
first, due to pkg-config not finding output files from the first library.
OK, I said, and did PKG_CONFIG_PATH=... and export PKG_CONFIG_PATH before
executing cmake build. And this fixed the problem.
However then I tried to ease the job of whoever might be using this, and
tried setting the PKG_CONFIG_PATH inside the cmake script. But this does not
work. I did some tests, and indeed, configure executed as part of
ExternalProject does not see environmental variables set by cmake.
So, the question is, am I doing something wrong or is this cmake limitation?
Miki.
P.S. I am doing this on a Mac OSX Lion, but I expect it to work on Linux
without modifications.
