I have got the same issue.

Not sure how to solve it.

I built without tests -DIO2D_WITHOUT_TESTS=1

I built without tests -DIO2D_WITHOUT_TESTS=1

how did you did this. can u tell the steps with commands

[matt-tony]

Try to add it as a parameter to the cmake call. However, generally speaking, it is a bad idea to build without tests, imho...

how did you did this. can u tell the steps with commands

E.g. for building on Linux replace the line cmake --config Debug "-DCMAKE_BUILD_TYPE=Debug" .. with cmake --config Debug "-DCMAKE_BUILD_TYPE=Debug" -DIO2D_WITHOUT_TESTS=1 ..

I'm fairly new at this, but I find it silly that, even though this does the trick, CMake is nevertheless giving me a warning that Manually-specified variables were not used by the project: IO2D_WITHOUT_TESTS.
