V1.0 linux & Source Errors: "error while loading shared libraries: libQtOpenGL.so"

[eduncan911]

OS: Pop_OS 21.04 (Ubuntu 21.04)
Stanrdard user/non-system dev machine (meaning no "buildutils")

$ ./Plater
./Plater: error while loading shared libraries: libQtOpenGL.so.4: cannot open shared object file: No such file or directory

I run many other Qt apps though already. E.g. FreeCAD.

I also tried to pull down the source. However, upon compiling I get this error:

$ mkdir build
$ cd build/

CMake Error at gui/CMakeLists.txt:25 (find_package):
  By not providing "FindQt5.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "Qt5", but
  CMake did not find one.

  Could not find a package configuration file provided by "Qt5" with any of
  the following names:

    Qt5Config.cmake
    qt5-config.cmake

  Add the installation prefix of "Qt5" to CMAKE_PREFIX_PATH or set "Qt5_DIR"
  to a directory containing one of the above files.  If "Qt5" provides a
  separate development package or SDK, be sure it has been installed.

Error log didn't hold much. Just some C++ source that was unable to include, most likely from the missing Qt above.

Can you try:

sudo apt-get install qtbase5-dev
sudo apt-get install qtdeclarative5-dev

And restart the build ?
