I have been using for the last 18 months the KDevelop appimage of version 5.6.1 successfully.  I use a specific cmake version located at /usr/local/bin/cmake.  No issues with the appimage.

I changed it in both the global location under settings -> configure kdevelop -> cmake as well as project -> configure project -> cmake -> show advanced -> cmake executable.  The project setting will not keep the executable I point to.  It always defaults back to /app/bin/cmake.

Hi Ryan,

Searching for "cmake" (with quotes) in KDevelop source code turned up two 
relevant results:
1. In cmakeutils.cpp:
     auto cmake = QStandardPaths::findExecutable(QStringLiteral("cmake"));
2. In usebuilder.cpp:
     QStringList ids = CMake::executeProcess(QStringLiteral("cmake"), 
QStringList(QStringLiteral("--help-command-list"))).split(QLatin1Char('\n'));

 From (2) the "cmake" program is passed to QProcess::start(const QString 
&program, const QStringList &arguments, QIODevice::OpenMode mode = ReadWrite)

In both cases the order of paths in the PATH environment variable should 
determine which executable is picked. So check the value of, then override PATH 
somehow. How to do that is a Flatpak, not KDevelop question.

Cheers,
Igor
