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?
I' m not really sure, but I think it is a CMake limitation that has been
discussed before:
When you do
set(ENV{PKG_CONFIG_PATH}
${CMAKE_INSTALL_PREFIX}/lib/pkgconfig/:$ENV{PKG_CONFIG_PATH})
I think that you are setting the environment for the current cmake
process and all it' s child processes.
The problem is that when you use ExternalProject_Add() you are building
a Makefile that will be processed at build time whwn you invoke make
(or a XCode ide processing)
That process is NOT a child of your cmake, so the env is lost
As far as I know, there is (unfortunately) no ENV clause in
ExternalProcess, so the only (ugly) workaround that I have found is to
define a wrapper of the two configure and make processes that pass the
env you need like:
1) using the included pkgconfig_env.cmake
2) calling the wrapper script as I' ve tried to show subsequently by
modifying your second call
There could be a simpler way in your case, but I' ve included this as is
what I' m using for packaging external libraries.
I would really like to have an ENV clause in ExternalProcess to force
all the called steps to have a defined environment

P.S. I am doing this on a Mac OSX Lion, but I expect it to work on
Linux without modifications.
