Can build a trivial project with Meson but not with CMake

I want to get two executables from my C++ source code (test and release). I have two main() functions in two separate C++ files.

With the Meson build system it is easy: 

project('PrjName', 'cpp')

mainSrc = ['header1.hpp', 'source1.cpp', 'source2.cpp']
testSrc = ['header2.hpp', 'source2.cpp', 'test.cpp']

mainExe = executable('prjName', mainSrc)
testExe = executable('prjNameTest', testSrc)

I could not get the same with CMake:

cmake_minimum_required(VERSION 3.10)
project("PrjName")

set(SOURCES
    "header1.hpp"
    "source1.cpp"
    "source2.cpp"
)

set(TEST_SOURCES
    "header2.hpp"
    "source2.cpp"
    "test.cpp"
)

add_executable("prjName" ${SOURCES})
add_executable("prjNameTest" ${TEST_SOURCES})

I get the first executable (prjName), but not the second, with the error:

Multiple definition of 'main'

However, the main() functions are defined in "source1.cpp" and "test.cpp", so there should be no conflict.

How can I fix this issue, considering that as it seems from the Meson build the code should be fine?

Building the same code on a different PC, I had no such issue.

I would close/delete this question.
