コードの静的ビルドを作成したい (このコードをサーバー上で実行したい) と、奇妙な問題が発生します。

私のcmakeは次のようになります。
cmake_minimum_required(VERSION 2.8.9)
set(CMAKE_MODULE_PATH ${CMAKE_SOURCE_DIR}/cmake)
project(crypto)
set(PROJECT_NAME "crypto")
find_package(NTL REQUIRED)
include(CheckCXXCompilerFlag)
CHECK_CXX_COMPILER_FLAG("-std=c++11" COMPILER_SUPPORTS_CXX11)
CHECK_CXX_COMPILER_FLAG("-std=c++0x" COMPILER_SUPPORTS_CXX0X)
if(COMPILER_SUPPORTS_CXX11)
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11 -pthread")
elseif(COMPILER_SUPPORTS_CXX0X)
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++0x -pthread")
else()
message(STATUS "The compiler ${CMAKE_CXX_COMPILER} has no C++11 support. Please use a different C++ compiler.")
endif()
SET(CMAKE_EXE_LINKER_FLAGS "-static -lntl -lgmpxx -lgmp -lm")
add_executable(crypto main.cpp elliptic_curve.cpp point.cpp lenstra.cpp pollard_algorithm.cpp ThreadPool.cpp)
target_link_libraries(crypto ${NTL_LIBRARY})
何が間違っているのか本当にわかりません。どんな助けにも感謝します。
アップデート：
gmp と ntl がインストールされています。
⋊> ~/D/gmp-6.1.0 ls ~/sw/lib/libntl.a
/home/piotr/sw/lib/libntl.a
⋊> ~/D/gmp-6.1.0 ls /usr/local/lib/libgmp.a
/usr/local/lib/libgmp.a
⋊> ~/D/gmp-6.1.0 ls /usr/local/lib/libgmpxx.a

行を削除すると：
SET(CMAKE_FIND_LIBRARY_SUFFIXES ".a")
SET(BUILD_SHARED_LIBRARIES OFF)
SET(CMAKE_EXE_LINKER_FLAGS "-static")
cmake から、コードを問題なく正常にコンパイルできます。しかし、サーバーでこのコードを実行するには静的コンパイルが必要ですが、現在のビルド設定ではこれが不可能です。理由はわかりません。
次のような適切な FindNTL.cmake ファイルもあります。
FIND_PATH(NTL_INCLUDE_DIR RR.h
HINTS
$ENV{NTLDIR}
PATH_SUFFIXES NTL include/NTL include
PATHS
~/sw #
