While building “Aspose.Email for C++ 19.3 Linux” using given build.sh, cmake uses the GNU compiler (GCC-6.5) but the GuessCompilerPrefix.cmake file expects visual studio compiler!
After building, there is linking error because the libraries: ‘libaspose_cpp_gcc65.so’ and ‘libAspose.Email.Cpp_gcc65.so’ must be built using visual studio compiler and therefore gives linking error while building on linux.
I have observed your requirements and have observed similar issue posted in another thread from you. I have shared my feedback with you over following link.
