Build Gimp from custom-path libraries
I'm installing Gimp (2.6.10) on Debian. The system has all the required libraries (dependencies) installed in the default directories, so giving to Gimp

./configure && make && make install
completes fine, and installs Gimp.

But I compiled some of the dependencies manually, for needed performance. These are GEGL, Glib, and BABL. All them are correctly installed in

--prefix /usr/handsoftware
I configure Gimp with these essential flags: (there are more flags to strip down unused features from the binary)

./configure --prefix=/usr/handsoftware/ PKG_CONFIG_PATH="../gegl/:../babl/" CXXFLAGS="-march=pentium4 -O3" CXXFLAGS="-march=pentium4 -O3"
where PKG_CONFIG_PATH points to the source directories of GEGL and BABL from which these libraries were compiled and installed. I don't know if this setting is correct nor required.

This ./configures correctly, but make fails pointing out that gegl.h is missing.

gegl.h is installed in two points in my system:
1) in the GNU include standard directory, where it's been installed by APT
2) in ../gegl/ , as pointed by PKG_CONFIG_PATH
I have to point Gimp to the manually-installed includes rather than to the ones installed by APT, as the formers are those compatible with the manually installed library. Can I do this?

I do not think PKG_CONFIG_PATH is an option to configure. I tbelieve configure is looking for it as an env var. Also, you cannot use relative paths, they must be full pathnames. Try this:

export PKG_CONFIG_PATH="full/path/to/gegl:/full/path/to/babl:$PKG_CONFIG_PATH"
./configure [options]

Most configure scripts should give you help with:

./configure --help
Hope this helps.
