Erro "faltando o separador"

Estava tentando usar o comando make no seguinte makefile:

# Install script for directory: /home/eldio/Downloads/g_mmpbsa

# Set the install prefix
if(NOT DEFINED CMAKE_INSTALL_PREFIX)
set(CMAKE_INSTALL_PREFIX "/opt/g_mmpbsa")
endif()
string(REGEX REPLACE "/$" "" CMAKE_INSTALL_PREFIX "${CMAKE_INSTALL_PREFIX}")

# Set the install configuration name.
if(NOT DEFINED CMAKE_INSTALL_CONFIG_NAME)
if(BUILD_TYPE)
string(REGEX REPLACE "^[^A-Za-z0-9_]+" ""
CMAKE_INSTALL_CONFIG_NAME "${BUILD_TYPE}")
else()
set(CMAKE_INSTALL_CONFIG_NAME "")
endif()
message(STATUS "Install configuration: \"${CMAKE_INSTALL_CONFIG_NAME}\"")
endif()

# Set the component getting installed.
if(NOT CMAKE_INSTALL_COMPONENT)
if(COMPONENT)
message(STATUS "Install component: \"${COMPONENT}\"")
set(CMAKE_INSTALL_COMPONENT "${COMPONENT}")
else()
set(CMAKE_INSTALL_COMPONENT)
endif()
endif()

# Install shared libraries without execute permission?
if(NOT DEFINED CMAKE_INSTALL_SO_NO_EXE)
set(CMAKE_INSTALL_SO_NO_EXE "1")
endif()

# Is this installation the result of a crosscompile?
if(NOT DEFINED CMAKE_CROSSCOMPILING)
set(CMAKE_CROSSCOMPILING "FALSE")
endif()

if(CMAKE_INSTALL_COMPONENT)
set(CMAKE_INSTALL_MANIFEST "install_manifest_${CMAKE_INSTALL_COMPONENT}.txt")
else()
set(CMAKE_INSTALL_MANIFEST "install_manifest.txt")
endif()

string(REPLACE ";" "\n" CMAKE_INSTALL_MANIFEST_CONTENT
"${CMAKE_INSTALL_MANIFEST_FILES}")
file(WRITE "/home/eldio/Downloads/g_mmpbsa/${CMAKE_INSTALL_MANIFEST}"
"${CMAKE_INSTALL_MANIFEST_CONTENT}")

e surgiu a seguinte mensagem de erro

cmake_install.cmake:4: *** faltando o separador. Pare.

alguma sugestão??

Olá.

O conteúdo deste arquivo não está na sintaxe de Makefile (ao menos não no padrão posix: http://pubs.opengroup.org/onlinepubs/009695399/utilities/make.html ).
