CMake could not find LibDL or LibMagic even though they are installed with apt

[NlGHT]

Hey,

I've been trying to build airwave, but for some reason cmake can't find LibMagic or LibDL. I have also tried to skip these and turns out it can't find X11 either. All of these packages I have installed already through apt (libmagic-dev, libx11-dev) and I'm running on Mint 19.1. Just wondering if anyone else seemed to encounter a similar issue or if there is something obvious I might be missing.

My terminal output shows this:

~/DownloadedZipApps/airwave$ cmake -DCMAKE_BUILD_TYPE="Release" -DCMAKE_INSTALL_PREFIX=/home/night/DownloadedZipApps/airwave-install

-- VST2 SDK headers are found in /home/night/DownloadedZipApps/airwave/VST2
-- Could NOT find LibDL (missing: LIBDL_LIBRARY) 
-- libmagic version: 5.32
CMake Error at /usr/share/cmake-3.10/Modules/FindPackageHandleStandardArgs.cmake:137 (message):
  Could NOT find LibMagic (missing: LIBMAGIC_LIBRARY)

Any help or pointers appreciated!
