[QGIS-Developer] Compiling against homebuilt GDAL

[Thomas Larsen Wessel]

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 git at 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?
