Hi Thomas,
Not sure if it is usefull, but some time ago I build (always in ~/git/foo) and
install (always in ~/bin/foo) PROJ, GDAL and then build QGIS (in
~/git/qgisgdal) with those.
This is what I then use:
cd /home/richard/git/qgisgdal;
export
LD_LIBRARY_PATH=/home/richard/bin/qgis/qgisgdal/debug/lib/:/usr/lib/grass76/lib/;export
LD_LIBRARY_PATH=/home/richard/bin/gdal/lib:/home/richard/bin/proj/lib:$LD_LIBRARY_PATH
mkdir build;cd build;ccmake -DBUILD_TESTING=FALSE -DENABLE_TESTS=OFF
-DWITH_SERVER=TRUE -DWITH_3D=TRUE
-DCMAKE_INSTALL_PREFIX=/home/richard/bin/qgis/qgisgdal/debug
-DWITH_QWTPOLAR=OFF -DCMAKE_BUILD_TYPE=Debug
-DPROJ_INCLUDE_DIR=/home/richard/bin/proj/include/
-DPROJ_LIBRARY=/home/richard/bin/proj/lib/libinternalproj.so.15
-DGDAL_CONFIG=/home/richard/bin/gdal/bin/gdal-config
-DGDAL_INCLUDE_DIR=/home/richard/bin/gdal/include/
-DGDAL_LIBRARY=/home/richard/bin/gdal/lib/libgdal.so
-DQT5_3DEXTRA_LIBRARY=/usr/lib/x86_64-linux-gnu/libQt53DExtras.so
-DCMAKE_PREFIX_PATH=/home/richard/git/qgisgdal/external/qt3dextra-headers/cmake
-DQT5_3DEXTRA_INCLUDE_DIR=/home/richard/git/qgisgdal/external/qt3dextra-headers
..
Then to run QGIS you also have to make sure that QGIS picks up the right libs
by using the LD_LIBRARY_PATH above.
Hope this is helpful.
Regards,
Richard Duivenvoorde

I have successfully built QGIS and GDAL (3.7.2) separately. Now I want to build
QGIS against this GDAL. This is what I tried:
git clone g...@github.com:qgis/QGIS.git
cd QGIS
mkdir build
cd build
GDAL_DIR=/home/velle/gdal3.7.2/build cmake ..
The output contains the following error for GDAL:
CMake Error at /home/velle/gdal-3.7.2/build/GDALConfig.cmake:24 (include):
include could not find requested file:
/home/velle/gdal-3.7.2/build/GDAL-targets.cmake
Call Stack (most recent call first):
cmake/FindGDAL.cmake:16 (find_package)
CMakeLists.txt:365 (find_package)
Could someone please tell me if I'm even doing it right?
You need to *install* GDAL first. You can't just point QGIS to the GDAL build
directory
So in the GDAL build directory, do "cmake ..
-DCMAKE_INSTALL_PREFIX=$HOME/install-gdal-3.7.2 ; make -j$(nproc); make install"
and then when configuring QGIS, use GDAL_DIR=$HOME/install-gdal-3.7.2 . I'm not totally
sure about that last part. may require tweaking. you could alter the PATH to point to
$HOME/install-gdal-3.7.2/bin so that "gdal-config" from your installed GDAL is
picked up
