hi,
my program down for http://aul12.github.io/SerialToolbox/serialtoolbox.deb
run it, output :

$ SerialToolbox
terminate called after throwing an instance of 'std::runtime_error'
what(): Could not find ui file

git clone sourcecode and cmake build

$ cmake ..
CMake Error at CMakeLists.txt:25 (find_package):
By not providing "FindQt5Quick.cmake" in CMAKE_MODULE_PATH this project has
asked CMake to find a package configuration file provided by "Qt5Quick",
but CMake did not find one.

Could not find a package configuration file provided by "Qt5Quick" with any
of the following names:

Qt5QuickConfig.cmake
qt5quick-config.cmake

Add the installation prefix of "Qt5Quick" to CMAKE_PREFIX_PATH or set
"Qt5Quick_DIR" to a directory containing one of the above files. If
"Qt5Quick" provides a separate development package or SDK, be sure it has
been installed.
