# The C files in tests/src directory contain test code shared among test suites
# and programs. This shared test code is compiled and linked to test suites and
# programs objects as a set of compiled objects. The compiled objects are NOT
# built into a library that the test suite and program objects would link
# against as they link against the mbedcrypto, mbedx509 and mbedtls libraries.
# The reason is that such library is expected to have mutual dependencies with
# the aforementioned libraries and that there is as of today no portable way of
# handling such dependencies (only toolchain specific solutions).
#
# Thus the below definition of the `mbedtls_test` CMake library of objects
# target. This library of objects is used by tests and programs CMake files
# to define the test executables.
