Can't build GRASS and QGIS LTR with PDAL 2.6.1

[Ivan Mincik]

Describe the bug

When trying to build GRASS and QGIS with PDAL 2.6.1 in nixpkgs they both fail on trying to find PDAL.

GRASS

• GRASS error message (see: OSGeo/grass#3220 )

checking whether to use PDAL... yes
configure: error: *** Unable to locate suitable (>=1.7.1) PDAL library.

• Workaround

rm libpdalcpp.so
ln -s libpdalcpp.so.?? libpdalcpp.so

QGIS LTR

• QGIS error message

CMake Error at cmake/FindPDAL.cmake:76 (MESSAGE):
  Could not find PDAL
Call Stack (most recent call first):
  CMakeLists.txt:437 (find_package)

Both packages build fine with PDAL 2.5.6

Will likely be solved by #4267.

Unfortunately latest QGIS LTR (3.28.13) still can't find PDAL 2.6.2:

GRASS build is fixed by PDAL 2.6.2
