Linker error when building with PDAL from master

[uclaros]

When building wrench in Debug, against PDAL's master branch in Release (after PDAL/PDAL#4888), the build fails while linking:

/usr/bin/ld: CMakeFiles/pdal_wrench.dir/src/clip.cpp.o: in function `pdal::Polygon::Polygon(void*)':

Does it fail in CI? Debug builds only? This ticket doesn't give enough detail.

This seems strange as the deleter is exported. A small test program with the build commands would be helpful.

Whoops, sorry for the spartan report, was in a hurry!

This is a local build, tried building wrench in Debug using PDAL master branch build. Apparently my PDAL build was forgotten to Release which seems to trigger the link error.
Did some more testing and switching PDAL to Debug too fixed it. Also setting wrench to Release fixed it.
So:

• wrench Release + PDAL Release: OK
• wrench Release + PDAL Debug: OK
• wrench Debug + PDAL Debug: OK
• wrench Debug + PDAL Release: Linker error

Is that expected?
