[QGIS-Developer] building QGIS without external/pdal-wrench

[Richard Duivenvoorde]

Hi,

I'm trying to package/install PDAL (for Debian), but after installing pdal libs I fail to install QGIS because (I think) changes in the interface or types or so???

Is there a way/flag to not use the extern/pdal_wrench dir?

Then I tried to 'fix' that by cleaning up the extern/pdal_wrench dir and commenting out the lines in src/providers/pdal/CMakeLists.txt which point to that dir...

But then I get:

Any pointers appreciated...
