Removing libQt5Core.so.5 dependency

Bardfast

Any help would be much appreciated.

On Linux, how do I remove all Qt library dependences from a C++ project that does not explicitly call any Qt methods or libraries?
Specifically, if I run ldd against the binary it shows libQt5Core.so.5 as a dependency.

linux-vdso.so.1 (0x00007ffe3abc4000)

My Qt Creator project looks something like the following …

TARGET = SampleApp
TEMPLATE = app

CONFIG += cmdLine
CONFIG += c++17
CONFIG -= app_bundle

DEFINES += BOOST_SIGNALS_NO_DEPRECATION_WARNING

LIBS += -L/usr/lib/
-L/usr/local/lib/
-lssl -lcrypt -lcrypto -lz -ldl -lcurl -ludev -lssh

INCLUDEPATH += $(MY_ROOT)

HEADERS +=
../../../build/TvlBuildDetails.h
../../../common/lib/LibCommandLine.h
src/Installer.h
src/Setup.h

SOURCES +=
../../../build/TvlBuildDetails.cpp
../../../common/lib/LibCommandLine.cpp
src/Installer.cpp
src/Setup.cpp
src/main.cpp

@Bardfast Try to add:

CONFIG -=qt

Or:

QT -= core
