vs19_pch_problem

This repo illustrates a problem with compiling single files within a project using precompiled headers.

Building from inside VS

When building from inside Visual Studio the compilation fails due to mismatch of precompiled header and redefinitions of macros like WIN32.

1. Build project
2. Compile CMakeProject2.cpp

Building from command line

When building from the command line (cmd.exe) everything works as expected.

cd ..\build\x64-debug
ninja
del CMakeProject2\CMakeFiles\CMakeProject2.dir\CMakeProject2.cpp.obj
ninja C:\Users\pg\source\repos\CMakeProject2\CMakeProject2\CMakeProject2.cpp^^
