Build failing with LIQUID_LIBRARIES error

[TJNII]

Good evening:

I'm attempting to rebuild my CubicSDR Docker container and the compile is failing with the following error:

CMake Error: The following variables are used in this project, but they are set to NOTFOUND.
Please set them or make sure they are set and tested correctly in the CMake files:
LIQUID_LIBRARIES
    linked by target "CubicSDR" in directory /src/CubicSDR

The change date on https://github.com/cjcliffe/CubicSDR/wiki/Build-Linux is several months before my last successful build on 2020-06-03 so I don't believe I missed a documentation update, but please let me know if there was a breaking change I need to update my build to account for.

Here is an exerpt of my Dockerfile with the build steps, the last build step posted is the one failing:

Hi all,

i ran into the same issue under Ubuntu 20.04.01.

cmake ../ -DCMAKE_BUILD_TYPE=Release -DwxWidgets_CONFIG_EXECUTABLE=~/Dev/wxWidgets-staticlib/bin/wx-config 64 bit compiler detected CMake Warning (dev) at /usr/share/cmake-3.16/Modules/FindOpenGL.cmake:275 (message): Policy CMP0072 is not set: FindOpenGL prefers GLVND by default when available. Run "cmake --help-policy CMP0072" for policy details. Use the cmake_policy command to set the policy and suppress this warning.

FindOpenGL found both a legacy GL library:

OPENGL_gl_LIBRARY: /usr/lib/x86_64-linux-gnu/libGL.so

and GLVND libraries for OpenGL and GLX:

OPENGL_opengl_LIBRARY: /usr/lib/x86_64-linux-gnu/libOpenGL.so
OPENGL_glx_LIBRARY: /usr/lib/x86_64-linux-gnu/libGLX.so

OpenGL_GL_PREFERENCE has not been set to "GLVND" or "LEGACY", so for compatibility with CMake 3.10 and below the legacy GL library will be used. Call Stack (most recent call first): CMakeLists.txt:170 (find_package) This warning is for project developers. Use -Wno-dev to suppress it.

Retried this today and it passed. Assuming it was fixed in one of the updates since I opened this.
