Estou construindo um projeto de dependência com o comando cmake ExternalProject_Add:

include(ExternalProject)
...
set(COMMON_BASE_PROJECT_DIR ${CMAKE_CURRENT_SOURCE_DIR}/../CommonBase)

ExternalProject_Add(CommonBaseProject
  SOURCE_DIR ${COMMON_BASE_PROJECT_DIR}
  BINARY_DIR ${COMMON_BASE_PROJECT_DIR}/build
  INSTALL_COMMMAND ""
)   

include_directories(${CMAKE_CURRENT_SOURCE_DIR}/include)
include_directories(${COMMON_BASE_PROJECT_DIR}/include)

add_library(
    ${LIBRARY_NAME}
    SHARED
    ${SRC_FILES}
    ${INCLUDE_FILES}
)

target_link_libraries (Bios ${COMMON_BASE_PROJECT_DIR}/build/libCommonBase.dll)
add_dependencies(Bios CommonBaseProject)

mas eu recebo erro:

[100%] Linking CXX shared library libCommonBase.dll
[100%] Built target CommonBase
[ 50%] Performing install step for 'CommonBaseProject'
make[3]: *** No rule to make target 'install'.  Stop.

Não preciso fazer a instalação, então minha pergunta é: como desabilitá-la?
