I’m stuck compiling FC on macOS Big Sur. The build breaks with an error not finding certain XercesC libraries. But these libraries are installed and the path is even found by the CMake preparation process.
I postet this issue in the FreeCAD forum under https://forum.freecadweb.org/viewtopic.php?f=4&t=60663, but found no help. I would appreciate if anyone here at StackOverflow could verify this error or better yet have a hint for a solution. Thanks in advance.
System Info:
Complete steps for the build prozess:
# install freecad dependencies via homebrew
brew tap freecad/freecad
brew install eigen
brew install --only-dependencies freecad --with-packaging-utils
# Freecad source is located in folder freecad-source/
# setup the build folder and change into newly created folder
mkdir -p freecad-build
cd freecad-build
# export path to installed dependencies

Now I start the build process with the following steps:
# set path to icu4c
# see https://forum.freecadweb.org/viewtopic.php?p=507588#p507588
export LIBRARY_PATH="/usr/local/opt/icu4c/lib"
#start the build according to the last line of the cmake summary report
cmake --build /Users/dirkolbrich/freecad/freecad-build/release
The build errors shortly before finish with an error of not finding the XercesC library files:

make: *** [all] Error 2
The not found files exist under the specified path at /usr/local/include/xercesc/framework/XMLPScanToken.hpp according to the summary report and verified manually.
Even adding -DXERCESC_INCLUDE_DIR=/usr/include/xercesc to the cmake command does not help.
There is a typo in the build script.
The final report prints XercesC_INCLUDE_DIRS,
but the CMakeLists.txt for that subdirectory uses XERCESC_INCLUDE_DIR.
I suggest you fix the typo (to XercesC_INCLUDE_DIRS) in src/Mod/Measure/App/CMakeLists.txt and file a pull request.
