When doing a cmake on a plugin I get the error: Could NOT find ZeroMQ (missing: ZeroMQ_FOUND) I just installed gazebo 9. I had been using gazebo 7.

The detail: iMac:build arnoldbail$ cmake .. CMake Warning (dev) in CMakeLists.txt: No project() command is present. The top-level CMakeLists.txt file must contain a literal, direct call to the project() command. Add a line of code such as

project(ProjectName)

near the top of the file, but after cmakeminimumrequired().

CMake is pretending there is a "project(Project)" command on the first line. This warning is for project developers. Use -Wno-dev to suppress it.

CMake Warning (dev) at /usr/local/Cellar/cmake/3.18.1/share/cmake/Modules/FindPackageHandleStandardArgs.cmake:273 (message): The package name passed to find_package_handle_standard_args (PkgConfig) does not match the name of the calling package (gazebo). This can lead to problems in calling code that expects find_package result variables (e.g., _FOUND) to follow a certain pattern. Call Stack (most recent call first): /usr/local/Cellar/cmake/3.18.1/share/cmake/Modules/FindPkgConfig.cmake:59 (findpackagehandlestandardargs) /usr/local/lib/cmake/gazebo/gazebo-config.cmake:30 (include) CMakeLists.txt:4 (find_package) This warning is for project developers. Use -Wno-dev to suppress it.
