Error in build: Invalid numeric armument '/Wunused'

[ESui2]

Hi,

I seem to have a similar problem as been stated before. However instead of the /Wunused-macros I solely have a /Wunused invalid argument. I cloned the repository on my windows system and ran CMake in MSVS that returned the following error:

PS C:\Users\user\openGJK\openGJK> cmake --build build

Full output of all steps are:

Does anyone happen to know what the problem could be? Perhaps I missed a step?

@ESui2 I created a branch with a quick fix. Can you please test it before I merge it? I don't have MSVS to test it myself.. what CMake version are you using ?

[ESui2]

Within the examples\c\main.c file the lines "int readinput()" and "int main()" had the word "int" on a separate line, which tripped up the initial parsing of this file on my build. After this and with your branch implementation i got 1 definite error as shown underneath.

I am working with CMake 3.28.1

@ESui2 could you please try again? I don't understand why I left the link to the math library not guarded, but that causes you link error

Please let me know

[MattiaMontanari]

@ESui2 i pushed new charges for you to test, pull the latest version and let me know. Thanks
