Bug Report

Please answer the following questions for yourself before reporting a bug.

• I checked the documentation and the forum but found no answer.
• I checked to make sure that this issue has not already been filed.

Environment

Select the following information.

• DART version: master and 6.9.2
• OS name and version name(or number): Arch
• Compiler name and version number: GCC 9

Expected Behavior

CMake config succeeds

Current Behavior

Findings in gazebosim source code:

• find_package(DART ${GAZEBO_DART_MIN_REQUIRED_VERSION} REQUIRED CONFIG)
• No custom FindDART.cmake

However, the find_package(DART) results in the following error:

CMake Error at catkin_ws/install/share/dart/cmake/DARTFindBullet.cmake:15 (if):
  if given arguments:

    "WIN32" "AND" "optimized" "IN_LIST" "BULLET_LIBRARIES" "AND" "debug" "IN_LIST" "BULLET_LIBRARIES"

  Unknown arguments specified

  cmake/SearchForStuff.cmake:165 (find_package)
  CMakeLists.txt:147 (include)

This happens for master, NOT 6.9.2 (in AUR). The change is clearly introduced in 6b023c2994294d6eb1b95e2242e39ba7e9f02427.

Steps to Reproduce

Steps for reproducing the issue. 0. Install DART

1. Clone Gazebo (head) and compile
2. Failure!!!

I’m sorry I can’t create a smaller CMakeLists.txt only Min Rep Example
