2 hours ago Mayo builds fine with OpenCascade 7.8 on Windows, see the current Windows CI status: https://github.com/fougue/mayo/actions/runs/11795444647
Mayo cmake script just doesn't correctly identify your OpenCascade build
You built OpenCascade yourself, make sure you followed the whole procedure, especially the "install" step(consider the INSTALL_DIR variable of OpenCascade cmake script)
https://dev.opencascade.org/doc/overview/html/build_upgrade__building_occt.html
If it still doesn't work then just install and use prebuilt OpenCascade binaries: https://dev.opencascade.org/release/open-cascade-technology-780
I am compiling mayo develop branch against opencascade7.8.0 on X64 Windows and cmake failed to detect opencascade's version.
Selecting Windows SDK version 10.0.22621.0 to target Windows 10.0.22631. GIT_EXECUTABLE=D:/Git/bin/git.exe Mayo_PostBuildCopyRuntimeDLLs_DefaultValue=ON Qt version 5.14.2 OpenCascade version .. glTF reader disabled because OpenCascade < v7.4 OBJ reader disabled because OpenCascade < v7.4 glTF writer disabled because OpenCascade < v7.5 OBJ writer disabled because OpenCascade < v7.6 VRML reader disabled because OpenCascade < v7.7 Configuring done (0.5s)
And when building the generated .sln, VS2022 met with error: LINK : fatal error LNK1104: cannot open file“D:\library\OCCT\OCCT-7_8_0\build\win64\vc14\lib\TKIGES.lib” However, the TKIGES.lib has been renamed to TKDEIGES.lib in opencascade7.8.0, so probably the cmakelists.txt is to be modified.
