CMake Error at /usr/share/cmake-3.13/Modules/FindPackageHandleStandardArgs.cmake:137 (message):
  Could NOT find Polyclipping (missing: Polyclipping_INCLUDE_DIRS)
Call Stack (most recent call first):

  CMakeLists.txt:20 (find_package)


-- Configuring incomplete, errors occurred!


Root cause:

$  cat /usr/lib/x86_64-linux-gnu/pkgconfig/polyclipping.pc
prefix=/usr
exec_prefix=/usr
libdir=lib/x86_64-linux-gnu
sharedlibdir=lib/x86_64-linux-gnu
includedir=include
...


I would suspect the #915267 change as root cause.
