Using cmake.js with google test for testing a node.js addon - googletest

Question

I am trying to test a node-js addon (built with cmake-js) with google test.
I am building on Mac OS.
The addon target builds and runs ok, but I have problems with the googletest target.
I am getting linking errors related to undefined V8 methods.
In CMakeLists.txt I printed (with message) the variables CMAKE_JS_SRC and CMAKE_JS_LIB and they are both empty. If CMAKE_JS_LIB is empty I don't see how target_link_libraries() should work to add the node/v8 library to my test executable...
If instead of using add_executable() I use add_library() the google_test target builds but of course I can not run it since it is not an executable anymore.
Can you help?
Below is my CMakeLists.txt:
make_minimum_required(VERSION 3.14)
include_directories(my_project)
set(CMAKE_CXX_STANDARD 14)
set(CMAKE_C_FLAGS "-Wno-pointer-sign -fno-signed-char -std=c99 -fpermissive")
set(CMAKE_CXX_FLAGS "-Wno-pointer-sign -fno-signed-char -std=c99 -fpermissive")
project (addon)
include(FetchContent)
FetchContent_Declare(
googletest
GIT_REPOSITORY https://github.com/google/googletest.git

include_directories(${CMAKE_JS_INC} "my_project/include/pkcs11/v2.40/")
file(GLOB SOURCE_FILES "my_project/*.c" "my_project/*.h" "my_project/*.cpp")
add_library(${PROJECT_NAME} SHARED ${SOURCE_FILES} ${CMAKE_JS_SRC})
set_target_properties(${PROJECT_NAME} PROPERTIES PREFIX "" SUFFIX ".node")
target_link_libraries(${PROJECT_NAME} ${CMAKE_JS_LIB} )
## google_test
enable_testing()
file(GLOB TEST_FILES "test/*.cc" "test/utils/*.c")
add_executable(
my_project_google_test
${TEST_FILES)
)
target_include_directories(my_project_google_test
PRIVATE
test/utils/*.h
)
target_link_libraries(
my_project_google_test
PRIVATE
GTest::gtest_main
${CMAKE_JS_LIB}
)
include(GoogleTest)
gtest_discover_tests(my_project_google_test)

Answer 1

CMAKE_JS_LIB is empty everywhere except on Windows.
Install v8 from Homebrew if you haven't done it yet: brew install v8.
Link the app to v8
target_link_libraries(
my_project_google_test
PRIVATE
v8
)
Other v8 libraries can be required, you have not post all errors: v8_libbase v8_libplatform.
