My cmake file is
cmake_minimum_required(VERSION 2.8.4)
project(libtry CXX)
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")
set(EXE_NAME libtry)
file(GLOB_RECURSE MAIN_SRC_FILES "src/*.cpp")
add_library (Try SHARED ${MAIN_SRC_FILES})
set(SOURCE_FILES main.cpp)
add_executable(${EXE_NAME} ${SOURCE_FILES})
target_link_libraries(${EXE_NAME} Try)
This file works and creates the two files: a .so file and an executable and it works perfectly. The problem is even after removing the .so file, the executable is working normally which means that the executable is statically linked.
Why this is happening and why cmake is not dynamically using the .so file?

I am trying to use a few imported shared libraries in a project which is to be tested through GTest. If I create test executables manually (e.g. without GTest), everything works fine. However, when enabling executables that rely on GTest, the build crashes with the following error:
<path to build dir>/test_gtest: error while loading shared libraries: ./libDependencyL2.so: >cannot open shared object file: No such file or directory
CMake Error at /usr/share/cmake-3.24/Modules/GoogleTestAddTests.cmake:112 (message):
Error running test executable.

Output:

I am using CMake as the build system. Compilation and running take place on a x86 Ubuntu 20.04.

Unsuccessful solution attempts
Here is a list of things I have tried without success to solve the issue:
target_link_libraries on test_project/CMakeLists.txt
target_link_libraries(libDependencyLevel1 PUBLIC libDependencyLevel2) # INTERFACE and PRIVATE specifiers were also evaluated
link_directories on test_project/CMakeLists.txt
link_directories(${CMAKE_CURRENT_SOURCE_DIR}/lib)
Reasoning and questions
According to the error message shown in the beginning of this post, the build system is not finding the shared libraries needed when GTest is used. But why is this happening? And why not using GTest solves the linking error, even if the IMPORTED SHARED libraries are imported in the same way for building both executables?
Finally, what can I do to solve the building issue when using GTest?
I have application built in Ubuntu 14.04 / GCC 4.8 / CMake 2.8 with -static-libgcc and -static-libstdc++. ldd command shows:

I supposed -static flag will result in static linked application. It did not happen.
May anyone explain me why ?
I have makefile generated by Qt Creator - with -static switch build results in fully static application.
-static is different from -static-libgcc and -static-libstdc++ specifically in that -static does not assume static linking of standard libraries. Those two flags control this behavior.
To link statically with standard libraries, add those two flags to CMake CMAKE_EXE_LINKER_FLAGS variable.
It is from resulting CMakeLists.txt. I use -DSTATIC_LINKING=True when running CMake.

I want to build a c++ program that dynamically links the QT-Core library.
For this I am using the WSL as my build environment and CLion as my IDE.
When I compile this programm in the WSL (ubuntu_18.04) the linker does not find the QtLibrary but when I compile it in a docker container (ubuntu_18.04) the linker finds the library.
I am quite confused by this since it seems to me I have set the library search path correctly.
Anyone got any idea what might be causing this ?

I use CMAKE to link a program to SDL2, OpenGL and I compile tinyxml2 as a shared library. The resulting program binary is 1.4 mb but there's barely 1k lines of code in the program. I suspect some library is statically linked. I'd prefer they are linked as shared libraries. I tried with debug symbols on and off with:
cmake -DCMAKE_BUILD_TYPE=Debug .
and off:
cmake .
and resulting binaries are still 1.4 mb each, which is weird because debug should be bigger. Here is my CMakeLists.txt:
