and btw, the build finishes too quick
Here are the errors...
typedef HRESULT WINAPI (*SetProcessDpiAwarenessFunctionPointer) (int
C2059 sqPlatformSpecific-Win32.c:80 syntax error: '('
E0651 a calling convention may not be followed by a nested declarator.
The following change reduces build errors to 1...
typedef HRESULT (*SetProcessDpiAwarenessFunctionPointer) (int awareness);
but I'm not sure of the implications.
Could be "the parenthesis around the function name" 
Or "there's already a C standard function [of that name]" 
The Microsoft definition returns a BOOL .
sqInt ioSetCursorARGB(sqInt cursorBitsIndex, sqInt extentX, sqInt
extentY, sqInt offsetX, sqInt offsetY)
C2371 'ioSetCursorARGB': redefinition; different basic types
where sqInt is "long long".
but the function declaration is
int ioSetCursorARGB(sqInt bitsIndex, sqInt w, sqInt h, sqInt x, sqInt y);
After modifying that function declaration to return 'sqInt',
"Cmake > Build all" runs much longer
and ends up with 4 link errors (and 6600 warnings)
Pharo.exe LNK1120 - 1 unresolved external
Pharow.exe LNK1120 - 1unresolved external
sqMain.c.obj LNK2019 - unresolved external symbol _imp_osvm_main
referenced in function main
sqWin32Main.c.obj LNK2019 - unresolved external symbol _imp_osvm_main
referenced in function WinMain
I do see osvm_main is defined here...
but I'm stuck, I don't understand why its looking for "_imp_osvm_main"
I'd be glad if anyone can advise on this, and the two errors above.
