After downloading the latest Fast-CDR, I verified Fast-CDR's functionality by following the steps below：

git clone https://github.com/eProsima/Fast-CDR.git

cd Fast-CDR

mkdir build && cd build

cmake .. -DCMAKE_INSTALL_PREFIX=../install -D BUILD_TESTING=ON -D GTest_DIR=/usr/local

cmake --build . --target install

./test/cdr/UnitTests
