Hello,
I am trying to add libQGLViewer as dependency for Gazebo for Flatpak package for linux.
The filesystem of Flatpak use /app instead of /usr
I cannot build libQGLViewer because of this error.
x86_64-unknown-linux-gnu/bin/ld: cannot find -lGLU
Running ld -lGLU --verbose give me this.
GNU ld (GNU Binutils) 2.35.2
Supported emulations:
elf_x86_64
elf32_x86_64
elf_i386
elf_iamcu
elf_l1om
elf_k1om

I think that the correct directory should be /app/lib instead of /usr/lib.
How can I change this? Is it some path I can modify in QGLViewer.pro?
i tried using
ln -s /app/lib/libGLU.so /usr/lib/libGLU.so
but does not work simple because /usr/lib simply do not exist in Flatpak filesystem.
I tried,
export LDFLAGS=-L/app/lib
export LD_LIBRARY_PATH=/app/lib/
export LIBRARY_PATH=/app/lib/
but ld still looking into /usr, the same as above, or did I use it wrong?
Thank you.

Update.
I got it working now.
I don't know why, but flatpak prefer that I do something like this.
- name: libQGLViewer
buildsystem: qmake
subdir: QGLViewer
build-options:
env:
LIBRARY_PATH: "/app/lib:/usr/lib"
LD_LIBRARY_PATH: "/app/lib:/usr/lib"
config-opts:
- LIB_DIR=/app/lib
- INCLUDE_DIR=/app/include
- PREFIX=/app
sources:
- type: archive
url: http://www.libqglviewer.com/src/libQGLViewer-2.7.2.tar.gz
