Question

I\'m trying make a Visual Studio solution with CMake to compile the latest version of aseprite and CMake keeps giving me the:

No CMAKE_C_COMPILER could be fo         


        

Answer 1

Just in case it helps any one like me in future:

I have had this issue for 24 hours now, on 3 different 64-bit machines(Win7 , Windows 8.1 VM and WIn 8.1 laptop) - whilst trying to build WebKit with VS 2017.

The simple issue here is that the VC++ compiler (i.e cl.exe and it's dependent DLLs) is not visible to CMake. Simple. By making the VC++ folders containing those binaries visible to CMake and your working command prompt(if you're running Cmake from a command prompt), voila! (In addition to key points raised by others , above)

Anyway, after all kinds of fixes - as posted on these many forums- I discovered that it was SIMPLY a matter of ensuring that the PATH variable's contents are not cluttered with multiple Visual Studio BIN paths etc; and instead, points to :

a) the location of your compiler (i.e. cl.exe for your preferred version of Visual Studio ), which in my case(targeting 64-bit platform, and developing on a 64-bit host) is: C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\VC\Tools\MSVC\14.15.26726\bin\Hostx64\x64

b) and in addition, the folder containing a dependent DLL called (which cl.exe is dependent on): api-ms-win-crt-runtime-l1-1-0.dll - which on my machine is:

C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\Common7\IDE\Remote Debugger\x64

These two directories being added to a simplified and CUSTOM System Path variable(working under a Admin priviledged commmand prompt), eliminated my "No CMAKE_C_COMPILER could be found" and "No CMAKE_CXX_COMPILER could be found." errors.

Hope it helps someone.
