<p>Hi Stephen,</p>
<p><br>
</p>
<p>I am also interested in Kitware's response to your question. I don't use Qt Creator, but I help maintain several projects that use Visual Studio and MinGW gfortran via the CMakeAddFortranSubdirectory feature. This feature is somewhat limited and not really
maintained (in my experience).</p>
<p><br>
</p>
<p>Background: In my case, I use a heavily modified version of <span style="font-family: Calibri, Helvetica, sans-serif, EmojiFont, "Apple Color Emoji", "Segoe UI Emoji", NotoColorEmoji, "Segoe UI Symbol", "Android Emoji", EmojiSymbols; font-size: 16px;">CMakeAddFortranSubdirectory
that supports Xcode builds in addition to MSVC. I also have dependencies of the form mycpp.exe -> myf90.lib -> mycpp.lib -> msmpi.lib that standard <span style="font-family: Calibri, Helvetica, sans-serif, EmojiFont, "Apple Color Emoji", "Segoe UI Emoji", NotoColorEmoji, "Segoe UI Symbol", "Android Emoji", EmojiSymbols; font-size: 16px;">CMakeAddFortranSubdirectory
doesn't know how to deal with.</span></span></p>

I run the 'build' target via Visual Studio, the Fortran compiler is discovered by <span style="font-family: Calibri, Helvetica, sans-serif, EmojiFont, "Apple Color Emoji", "Segoe UI Emoji", NotoColorEmoji, "Segoe UI Symbol", "Android Emoji", EmojiSymbols; font-size: 16px;">CMakeAddFortranSubdirectory
only if gfortran.exe is in %PATH% (via find_program -- I believe that the default code only supports the name 'gfortran.exe'.) You might need to add <span style="color: rgb(33, 33, 33); font-family: Calibri, sans-serif; font-size: 14.6667px;"><span style="font-size: 12pt;">C:/Qt/Tools/mingw730_64/bin/
to your local path before running cmake for the project. I have found that </span><span style="font-family: Calibri, Helvetica, sans-serif, EmojiFont, "Apple Color Emoji", "Segoe UI Emoji", NotoColorEmoji, "Segoe UI Symbol", "Android Emoji", EmojiSymbols; font-size: 12pt;">CMakeAddFortranSubdirectory
isn't flexible. You may need modify it for your own needs. </span></span></span></span></span></p>

<p class="MsoNormal">I would like to try to use 64-bit gfortran to compile a project in which the rest of the code is compiled with Visual C++ 2017. I’ve read the netlib article (<a href="http://www.netlib.org/lapack/lawnspdf/lawn270.pdf">http://www.netlib.org/lapack/lawnspdf/lawn270.pdf</a>)
but it doesn’t address my problem, which is how to help CMake select the right Fortran compiler. The CMakeLists.txt file is launched from within Qt Creator.<o:p></o:p></p>
