I have downloaded source from url https://bitbucket.org/rmcantin/bayesopt/ and i have downloaded the MinGW compiler for Windows when I try to build the program the error is:
Please help me on this I have also deleted the old cache when I try to build the bayes optimization.

Answer 1

You could try to compile a simple C++ program first without CMake. E.g. store a simple main.cpp somewhere in your user directory C:\Users\<yourname>\Temp directory with following content:
int main()
{
return 0;
}
Now open CMD window in your C:\Users\<yourname>\Temp directory and run:
C:\MinGW\bin\gcc.exe main.cpp -o testprog
If an error popup appears that is saying something about a missing .dll, run following command in your CMD window and try to compile again:
set PATH=%PATH%;C:\MinGW\bin
If you had to run the last command, add the C:\MinGW\bin path permanently. After all it should be possible to run CMake with MinGW as compiler.

Answer 2

Verify that your MinGW compiler for Windows is able to build a simple program without CMake, for example: Hello World
When it works, clean your cache and try again.
