src package

[projdefensas]

Your FLIMbuilder.pro mentions file .cpp from ./src:

...
SOURCES += \
        src/main.cpp \
        src/mainwindow.cpp \
    src/common.cpp \
    src/mygraphicsview.cpp \
    src/markers.cpp \
    src/flim.cpp \
    src/mycombobox.cpp \
    src/orientation.cpp \
    src/runguard.cpp \
    src/myplaintextedit.cpp \
    src/graphnode.cpp \
    src/graphedge.cpp \
    src/projectiongraphicsview.cpp \
    src/projection.cpp
...

the issue is: where is the src package?
I tried running: !find . -name "main.cpp", but the file doesn't exist.
