Wt

Hi,

We are having issues when trying to build Wt on macOS Catalina 10.15.7

We are using GCC 11.

We tried adding :
//CXX compiler
CMAKE_CXX_COMPILER:STRING=/usr/local/Cellar/gcc/11.3.0/bin/g++-11

//A wrapper around 'ar' adding the appropriate '--plugin' option
// for the GCC compiler
CMAKE_CXX_COMPILER_AR:FILEPATH=/usr/local/Cellar/gcc/11.3.0/bin/gcc-ar-11

//A wrapper around 'ranlib' adding the appropriate '--plugin' option
// for the GCC compiler
CMAKE_CXX_COMPILER_RANLIB:FILEPATH=/usr/local/Cellar/gcc/11.3.0/bin/gcc-ranlib-11

//Flags used by the CXX compiler during all build types.
CMAKE_CXX_FLAGS:STRING=-std=c++11 -I/usr/local/Cellar/boost/1.78.0_1/include -L/usr/local/lib

//Flags used by the linker during all build types.
CMAKE_EXE_LINKER_FLAGS:STRING=-stdlib=libc++ -arch x86_64 -L/usr/local/lib

To the CMakeCache.txt

Here is a log of the issue. The library exists and is located in /usr/local/lib
